DISH-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 779,641, dated January10, 1905.

Application filed February 24, 1904- Serial No. 195,073.

To all whom it may concern:

Be it known that I, ERNEs'r ORosBY, a citizen of the United States,residing at Alexandria, Minnesota, have invented certain new and usefulImprovements in Dish-Washing Machines, of which the following is aspecification.

My present invention relates to improvements in dish-washing machines;and the object of the invention is to provide a simple, economical,durable, and effective machine in which dishes may be quickly and easilycleansed and thereafter dried without handling or removal from theapparatus. I have also aimed to so construct the device that the nu mberof parts within the apparatus and exposed to the action of thewashing-water shall be reduced to a minimum and of such a nature thatthey may be readily cleansed, thus making the device of anextremely-sanitary nature.

The invention is illustrated in the accompanying drawings, in whichFigure l is a central vertical section showing the apparatus with theparts in position for washing the dishes. Fig. 2 is a similar View withthe parts in position for draining and drying. Fig. 3 is a cross-sectiontaken on the line w of Fig. 1.

In the figures similar reference characters indicate the same partswherever used.

The numeral 6 indicates a main or water receptacle adapted to containthe cleansingwater. A second receptacle 7 is designed to hold the dishesto be washed and is of a size to adapt it to fit within the receptacle6, and its bottom is provided with aplurality of perforations 7 whichpermit the entrance of the water from the receptacle 6 into thereceptacle 7. A cage 8, which consists of vertical rods having thinupper and lower ends connected, respectively, to rings 8 and 8", restsremovably within the receptacle 7, the dishes to be washed beingpiledaround the cage. Within the cage is located a fan 10, carried by avertical shaft 9, journaled in a step-bearing 9 at the bottom and in theplate or bar 7 at the top, through which it projects. This shaft carriesat its upper end a gear-wheel 11, which meshes with a gear 12, mountedon a short shaft 13 and having an operating crank-han dle 14:.

In the operation of the device the receptacle 7 with the dishes piledaround the cage is placed within the lower receptacle, as indicated inFig. 1, and the rotation of the fan by the handle causes the water to beviolently agitated and forced around among the dishes, whereby they areeffectually cleaned. After this action has been continued for a desiredlength of time the receptacle 7 is removed from the receptacle 6 andsupported above the same by a perforated plate 15, which is preferablyof slightly-conical shape, and in this position the dishes are allowedto drain, after which the fan may be rotated to force a current of airaround among the dishes to dry the same.

If desired, a cover 16 may be used to prevent splashing over of theWater during the Washing operation.

Having thus described my invention, what I claim is In a dish-washingmachine an outer waterreceptacle, an inner receptacle having aperforated bottom, a cylindrical cage centrally disposed within theinner receptacle, a vertical shaft journaled centrally within said cage,a plurality of radial wings or blades carried by said shaft, means forrotating said shaft, and means for supporting the inner receptacle abovethe outer to permit drainage of the dishes and drying thereof,substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
